PRlNTiNG-PRESS.

SPECIFICATION forming part of Letters Patent No. 772,632, dated October 18, 1904 Application filed December 21, 1983. Serial 1in. 186,923. (No modehl To (LZ wwnt it Tnay concern:

Be it known that I, Amos W. Pnocron, of Billerica, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Printing-Presses, of which the following is a specification.

This invention relates to printing-presses adapted specially for printing rnenn-enrds and to be operated by hand. The invention has for its object to provide a. simple and effective printing-press adapted to be operated with reasonablernpidity and to produce printing of satisfactory quality.

The invention consists inthe improvements which I will now proceed to describe and claim.

Ot' the accompanying drawings, forming a part of this specification, Figure 1 represents n top pian view of a press embodying my invention. Fig. 2 represents a side elevation of the same. Fig. 3 represents esection on line 3 3 of Fig. 1. Fig. 4 represents a seetion on line 4 4 of Fig. 1. Fig. 5 represents a view similar to Fig. 3, showing the machine nt a different stage of the operation. Fig. 6 represents a section on line 6 6 of Fig. 1. Fig. 7 represents a section on line 7 7 of Fig. 5. Fig. 8 represents an end elevation of the machine. Fig.' 9 representsasection on line 9 9 oi Fig. 1. Figs. 10, 11, 12, 13, and 14 represent views of details hereinafter referred to.

The seme reference characters indicate the seme parts in all the iigures.

In the drawings, a represents abase or bed to which is niiixed a form which ineindes the movable type Z1', from which the impression is made when the machine is operated.

c represen ts n frame which is provided with trunnions c', jonrneled in bearings cs on a slide or carriage, which, es here shown, is composed of two parallel bers or slides s s. which nre movable in guides in the base e. The treme c is provided with en inking-roller (l and an impression-roller e and is movable reletively to the form in such manner that the rolls d end e will cooperate elternateiy with the form and move across the ietter, the inking-roll d being in contact with the form and applying ink to the type, while the impression-roll e acts to press the paper against the inked type. The arrangement of the frame and rolls d end e is sncli that when the frame, which is adapted to tilt, is in the position shown in Figs. i2, 3, end 4 the inkingroll is depressed and is in position to ink the type when the carriage is moved over the form, the impression roll being' elevated. When, however, the frame is in the position shown in Figs. 5 and 6, the impression-roll is depressed in position to cooperate with the form in eiecting en impression on a sheet ot' paper when the carriage is moved over the form, the inking-roller being raised.

Means operated by the'movements of the carriage over the form are provided whereby when the carriage reaches one end of its movement it is automatically tipped to one oi' the positions above described and when it reaches the opposite end ot' its movement is nutomatically tipped to the other position. The means shown for automatically tipping the framev in this embodiment of my invention comprise eers or lugs f, which are supported by theearriage and havealimited independent endwise movement permitted b v :t block j". affixed to the carriage and occupying a slot f2 in the lug f, seid block being shorter than the slot, While the upper and lower wells of the slot are adapted to slide on the block. The enr f is provided with two inclined fncesfxf'.

g g represent arms afrixed to the trnnnions of the frame c and arranged to cooperate with the eerf, as hereinafter described. lWhen the carriage is at the end of its movement, (shown in Figs. 3 and 4,) the erm q projects below one end of the cerf. the arm g being raised above said eer. The inking-roll is therefore in position to copcrnte with the form when the carriage is moved in the direction indicated by the arrow on Fig. S.

When the carriage approaches the oppositeA end oi' its movement, the treme c being in the position indicated in Figs. 3 and L1, the projection fi on the eerfstrikes a fixed stop A, attached to the base e. The movement of the ear f is thus arrested just before the co1npletion of the movement of the carriage. The completion of the movement of the earriage after the arrest of the enr f causes the IOO arm y] to be swung upwardly by the earf, thus tilting the frame c to the position shown in Figs. 5 and 6, the arm g' being depressed. 'lhe impression-roll is now in position to cooperate with the form during the opposite movement ol' the carriage, which 1 will term the "printing" movement to distinguish it from the above-described inking movement. l'Vhcn the carriage nearly reaches the end of its printing movement, the projection f on the ear f strikes another ixed stop The earf' is again arrested before the completion of the movement of the carriage, so that the arm y is raised and the frame is returned to the position shown in Figs. 3 and 4.

It will be seen, therefore, that at the end of cach movement of the carriage one of the rollers is moved into and the other out of its operative relation to the form; but while the carriage is moving the frame carrying the rollers is locked in its tilted position by the arms g and g, which rest alternately upon the top of the lugf at each side of the machine, such arm resting upon the end of the upper surface of the lug, as shown in Figs. 3 and 5. The carriage may be reciprocatcd by any suitable means. 1 have here shown a shaft e', journaled in bearings affixed to the base and extending crosswise of the same, said shaft being provided with an operating crank or handle 2" and with gears t2, meshing with rack-teeth t", formed on the bars S, composing the carriage. The rotation of the shaft 2i causes the carriage to move endwise, as will be readily seen.

I prefer to provide means independent of the form for causing the rotation of the rolls when they are cooperating with the form, the independent rotation of the rolls preventing them from dragging on the type, as they would have a tendency to do if the frictional Contact between the rolls and the type Were relied upon to rotate the rolls. The preferred means for causing the independent rotation of the rolls comprise friction-wheels 7c it', aiiixed to the shafts of the rolls (l e and tracks m m, aliixed to the base, the said tracks having frictional faces m, which may be of rubber or any other suitable material. When each roll is in its operative position, the friction-wheels connected with it, are in frictional engagement with the tracks fm, so that the roll is rotated when the carriage is in motion. The rolls are preferably provided wi th frictional tires k', of rubber or other suitable material, as shown in Fig. 13. In Fig. 14 I show a luodilication in which the roll-rotating means comprise gears Zz, substituted for the rolls u, and rack-toothed tracks m2, substituted for the tracks m.

o represents an ink-distributing roll, which is supported by bearings in the frame o and is in contact with theinking-roll.

The inking-roll d and the impression-roll e are prefcral'ily each made in two sections, as shown in Figs. 1, 8, and 9, the form being correspondingly divided, as indicated in Fig. 1. g1 y) represent elastic bands which are attached to suitable supports at opposite ends oi' the form and are arranged so that they stand normally slightly above the printingface of the type and support the paper out ot contact therewith, the bands yielding to permit the paper to be pressed against the type.

I claim- 1. A printing-press comprising a form,an oscillatory frame having an inking-roll and an impression-roll, said rolls being mounted in the frame on opposite sides of the pivot of said frame and adapted to cooperate alternatel y with the form, one of the parts termed the frame and form being movable relatively to the other to cause the alternating' coperation of said rolls with the form, means being provided for locking said frame against oscillation during its movement relatively to the form.

2. A printing-press comprising a form, an oscillatory frame having an inking-roll and an impression-roll, one of the parts termed the frame and form being movable relatively to the other to cause the cooperation of the rolls with the form, and means operated by the movement of the said movable part for tilting the frame and causing the said rolls to cooperate alternately with the form, means being provided for locking said frame against oscillation during its movement relatively to the form.

3. In a printing-press, an oscillatory frame having an impression-roll, an inking-roll, and an ink-distributing device in contact with the inking-roll, and means for tilting said frame to make the inking-roll and the impressionroll alternately operative, means being provided for locking said frame against oscillation during its movement relatively to the form.

4. A printing-press comprising a form, a carriage movable over the form, a frame pivotally supported by said carriage, an inkingroll and an Aimpression-roll supported by the frame on opposite sides of the pivot thereof, and means for causing said rolls to become alternately operative in relation to said form, means being provided for locking said frame against oscillation during its movement relatively to the form.

5. A printing-press comprising a form, a carriage movable over the form, an oscillatory frame supported by the carriage, an

inking-roll and an impression-roll carried by said frame, arms aixed to the frame, a lug supported by the carriage and having a limited endwise movement thereon, and fixed stops arranged to arrest the lug, the said lug being formed to cooperate with the arms in tilting the frame.
